1 btnWeibo.setOnClickListener(new View.OnClickListener() {
2
3 @Override
4 public void onClick(View v) {
5 Intent intent = new Intent(LoginActivity.this,
6 SinaOAuthActivity.class);
7 startActivity(intent);
8 }
9 });
2. 载入认证页面，使用到的微博提供的url功能接口如下
1 public static String SINA_CONSUMER_KEY = "APP KEY";
2 public static String SINA_CONSUMER_SECRET = "APP SECRET";
3 public static String ACCESS_TOKEN = "";
4 public static String UID ="";
5 public static String PREFERENCES_NAME = "PACKET NAME"; //可在AndroidManifest.xml中查看
6 //认证页面url
7 public static String SINA_OAUTH = "https://api.weibo.com/oauth2/authorize?client_id="
8 + SINA_CONSUMER_KEY
9 + "&response_type=code&redirect_uri=http://www.sina.com"
10 + "&display=mobile";
11 //获取ACCESS TOKEN
12 public static String SINA_ACCESS_TOKEN = "https://api.weibo.com/oauth2/access_token?client_id="
13 + SINA_CONSUMER_KEY
14 + "&client_secret="
15 + SINA_CONSUMER_SECRET
16 + "&grant_type=authorization_code&redirect_uri=http://www.sina.com&code=";
17 //根据UID获取用户详细信息
18 private static String SINA_DETAIL_INFORMATION = "https://api.weibo.com/2/users/show.json?source="
19 + SINA_CONSUMER_KEY
20 + "&access_token="
21 + ACCESS_TOKEN
22 + "&uid="+UID;
3. 认证Activity代码如下， 登陆并获取用户信息后，与客户端进行通信，验证该用户（微博用户）是否已在本服务器注册，若已注册，直接登陆；若未注册，跳转至设置密码页面。之后在本地添加用户登录信息，即可免填写用户名密码直接登录。
1 public class SinaOAuthMainActivity extends Activity {
2 public WebView webview;
3 String code = "";
4 String result ="";
5 Intent intent;
6 public WeiboUser user = new WeiboUser();
7 public SPreferenceInf spi = new SPreferenceInf();
8 public static final String WEIBO_USER = "com.cse.myperson.WEIBO_USER";

64 new Thread(runnable_USER).start();
65 finish();
66 }
67 }
68 super.onPageStarted(view, url, favicon);
69 }
70 });
71 }
72

111 if(params[0].equals("existed")){

143 }
4. 这里有一个地方需注意，当采用WebView微博登陆后，每次登陆都会在本地保存COOKIEs登陆信息。这也是我在开发中遇到的一个难题，一个用户注册成功后，再次进入，直接提示认证成功。一开始认为是用SharedPreferences将登陆信息保存为xml文件了，但在/data相关路径下没有找到。之后转念一想，会不会存在数据库里了，最后在/databases路径下找到了webviewCOOKIEsChromium.db这个文件，在COOKIEs表中，看到了登陆信息。 认证成功后，调用这个方法即可：
1 public static void removeCOOKIE(Context context) {
2 COOKIESyncManager.createInstance(context);
3 COOKIEManager COOKIEManager = COOKIEManager.getInstance();
4 COOKIEManager.removeAllCOOKIE();
5 COOKIESyncManager.getInstance().sync();
6 }
5. 基本的流程是这样，设置密码，登陆等可自己替换。
